Howdy, recently now my scooter has been “overheating” and not sure what it could be. After 100 miles, I brought it to Florida for a few weeks and it drove good. Once in a while the overheat light would come on and go into limp mode and I’d pull over and turn it off and then back on and would drive just fine for another week. Just randomly would do that. Fast forward to now I drove it up in Va beach all summer fine with no problems, took it out in February and March on some nice cool days and I can’t get more then 10 minutes on it till it overheats and goes into limp mode. To get home I have to turn the key off and back on while moving and keep doing that every 1-2 minutes till I get home. I replaced the coolant and made sure there weren’t any air bubbles but hasn’t fixed it. Not sure if I have the warranty left on it and the dealer is a good 1hr drive away. Anyone got any ideas? Thanks

Here are your troubleshooting paths per the Factory Service Manual: -Coolant level low -Thermostat stuck closed -Excess carbon build up in combustion chamber -Poor quality fuel -Clutch slipping -Lean fuel mixture
+Bonus a bad water pump
I would suspect that the thermostat is stuck closed if it was always happening but with it being a bigger issue in colder months I think it could be bad fuel settings. If you're running REALLY lean you could have great power feeling but be making the engine really hot. An easy way to check would be to get one of those laser temp checkers that everyone seems to have with COVID going around and check your cylinder temperature. If it just climbs and climbs and your overflow starts to fill up you likely are overheating it and need to get it looked at.
+The water pump can easily be checked by swapping the small coolant line on top of the engine with a clear one and just watching the fluid. If it doesn't move, the pump died. Easy!
This should sort you out so you can go ride the ruck for more than 10 minutes at a time.
